TO ALL WHOM IT MAY CONCERN:

Be it known that we, Gnoncn Snirsox and WXLLIAM H. EDMUNDS, both of thetown of Waterbury, in the county of Washington, in the State of Vermont,have invented certain new and useful Improvements in Extinguishers forCool-Oil Burners; and the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrnwings, making a part of this specification, in whichr Figure 1represents:tvertical edge-view section through the Wick-tube, and thehinged cap, and mechanism for operating it to open and close.

Figure 2 shows a plan or top view of the some.

The object of our invention is to prevent the smoke and smell ofcoal-oil lumps, when the \vick is turned down to extinguish the light,and consists of it cap hinged to the socket on the top of the wick-tube,it couplingbur, and crank to open and close the cup by n. thumb-nut.

I To enable others to make and use our invention, we will describe itmore fully, referring to the drawings and the letters marked thereon. I

To the wick-tube A of a common coal-oil burner we fit a socket, a a, toslide over at the top, to which is hinged a concave cup, B, which isconnected with it crank, G, by u coupling-rod, b, so that by a quarterturn of the orztnk C the cap B is placed over the top of the wick-tubeA, and held firmly on; the crank-bur bearing against the tube so thatthe cap'C will press on the wick and close the tube, and can be turnedoil only by turning the nut d, changing the position of the crank C.

i Thus it will be seen that a, very perfect and efficient extinguishercan be put on to any of the ordinary coal-oil burners, at on expense sotrifling as not to add materially to the original cost, and which isvery desirable, both for safety and comfort. Another advantage incovering the wick when the light is not burning is that the wick doesnot dry up and is much easier relighted, and the gas is prevented fromgenerating and escaping by the evaporation of the oil: i 7

Having thus described our invention, what we claim :18 new, and desireto secure by Letters Patent, is-- The combination of the socket a awiththe hinged cup B, connecting-rod b, crank C, and wick-tube A,constructed and operating substantially in the manner herein described,for the purposes herein set forth.
